"I could imagine this being better for certain applications than a heli. To get a high forward speed with a heli, you have to tilt it forward a lot. Here, you just tilt the props, which lessens requirements on your camera mount."

"Aww, thanks for the long post. Sorry if I wasn't clear. I am aware of what the different components do, just wondered aloud why most guides mainly address the proportional part.
What are your thoughts on using fuzzy logic?"

"Why do pretty much all practical guides only address the P part of PID controllers? Is it that setting them up gives a good-enough response in real life?
Curt, I like your sim a lot and have been toying around with an autopilot (coupled to…"

"If you can, set up some smoothing on your throttle, so you don't go from full forward throttle to full backward throttle. Otherwise I could imagine quite a bit of stress on the prop, motor and motor mount."

"If you modded your EasyStar with ailerons, you can also do a controlled slip to slow down. Pull the ruder and use the ailerons to keep the wings horizontal. Or you can use your ailerons as speed brakes, but then you reduce your aileron travel."

"Yeah, I third the Paparazzi suggestion. Would like to hear what they're working on, where they're heading, what their thoughts on all the new open-source autopilots are & would like to hear a couple words about a common telemetry…"

"And atleast Paparazzi has a pretty good wind estimation, which might make it sufficiently precise for a soft landing. Cool stuff.
Geoffrey, how well does the OF algorith cope with flying above water or grass? I could imagine that it's a way too…"

"I wonder, could you come up with a clever way to use those to make landing smoother? Something about reading the apparent speed of the ground passing by (in pixels per second), comparing that to the actual ground speed, thus being able to measure…"

"Even though I don't know when I'll get to this (this is more of a side project), I will let you know. But I'm surprised that you aren't able to establish a tcp connection (which is streaming)... I know that some ports are…"

"I'll be watching your efforts intently - I am very interested in hooking stock cellphones up to MCU boards. I use bluetooth to connect between the phone and the board, then GPRS to connect to the remote server. One obstacle I ran into was that…"

We are getting started with ArduPilot and a R/C car to slowly warm up to the autonomous stuff and getting acquainted with ArduPilot. So to keep costs low, we will use my rooted T-Mobile G1 to provide GPS coordinates, accelerometer data, to make a movie, transmit over WiFi or GPRS/UMTS etc. Because I'm lazy I'll just cross-post from xda-developers. The beauty of it is that the serial output from… Continue
